Functionalisation of spruce O-acetyl-galactoglucomannans for barrier and composite applications

The increasing use of energy, food, and materials by the growing population in the world is leading to the situation where alternative solutions from renewable carbon resources are sought after. The growing use of plastics depends on the raw-oil production while oil refining are politically governed and required for the polymer manufacturing is not sustainable in terms of carbon footprint. The amount of packaging is also increasing. Packaging is not only utilising cardboard and paper, but also plastics. The synthetic petroleum-derived plastics and inner-coatings in food packaging can be substituted with polymeric material from the renewable resources. The trees in Finnish forests constitute a huge resource, which ought to be utilised more effectively than it is today. One underutilised component of the forests is the wood-derived hemicelluloses, although Spruce Oacetyl-galactoglucomannans (GGMs) have previously shown high potential for material applications and can be recovered in large scale. Hemicelluloses are hydrophilic in their native state, which restrains the use of them for food packaging as non-dry item. To cope with this challenge, we intended to make GGMs more hydrophobic or amphiphilic by chemical grafting and consequently with the focus of using them for barrier applications. Methods of esterification with anhydrides and cationic etherification with a trimethyl ammonium moiety were established. A method of controlled synthesis to obtain the desired properties by the means of altering temperature, reaction time, the quantity of the reagent, and even the solvent for purification of the products was developed. Numerous analytical tools, such as NMR, FTIR, SEC-MALLS/RI, MALDI-TOF-MS, RP-HPLC and polyelectrolyte titration were used to evaluate the products from different perspectives and to acquire parallel proofs of their chemical structure. Modified GGMs with different degree of substitution and the correlating level of hydrophobicity was applied as coatings on cartonboard and on nanofibrillated cellulose-GGM films to exhibit barrier functionality. The water dispersibility in processing was maintained with GGM esters with low DS. The use of chemically functionalised GGM was evaluated for the use as barriers against water, oxygen and grease for the food packaging purposes. The results show undoubtedly that GGM derivatives exhibit high potential to function as a barrier material in food packaging.

Steps towards more effective antitrust system in EU – The Damages Directive’s effect on victim’s right to compensation for antitrust harm

Kaikkien kansalaisten ja yritysten, jotka kärsivät vahinkoa Euroopan Unionin kilpailusääntöjen (SEUT 101 ja 102 artiklan) rikkomisen vuoksi, on voitava vaatia korvauksia vahingon aiheuttaneelta osapuolelta. Euroopan unionin tuomioistuin on ratkaisuillaan Courage ja Manfredi vahvistanut vahinkoa kärsineen oikeuden saada korvausta kärsimästään vahingosta. Suomessa kilpailuoikeudellista vahingonkorvausta koskeva oikeuskäytäntö on ollut vähäistä, vaikkakin viime aikoina on annettu muutama merkittävä vahingonkorvausratkaisu, näistä kenties tunnetuimpana asvalttikartelliratkaisu. Kilpailuoikeuden rikkomisesta vahinkoa kärsineet saavat kuitenkin vain harvoin korvausta kärsimästään vahingosta, mikä on ollut seurausta erilaisista lainsäädännöllisistä ja menettelyistä johtuvista esteistä jäsenvaltioiden säännöissä. Komission pitkään kestänyt lainsäädäntöhanke EU:n kilpailuoikeuden täytäntöönpanojärjestelmän selkeyttämiseksi päättyi marraskuussa 2014, kun Euroopan parlamentin ja neuvoston direktiivi tietyistä säännöistä, joita sovelletaan jäsenvaltioiden ja Euroopan unionin kilpailuoikeuden rikkomisen johdosta kansallisen lainsäädännön nojalla nostettuihin vahingonkorvauskanteisiin (2014/104/ EU) hyväksyttiin. Direktiivi julkaistiin Euroopan unionin virallisessa lehdessä 5. joulukuuta 2014, ja jäsenvaltioilla on 27.12.2016 asti aikaa implementoida direktiivi osaksi kansallista lainsäädäntöä. Direktiivin tavoitteena on EU:n kilpailusääntöjen tehokas täytäntöönpano sekä kilpailuoikeuden julkisoikeudellisen ja yksityisoikeudellisen täytäntöönpanon selkeyttäminen. Lisäksi direktiivi pyrkii varmistamaan, että vahingonkärsijät voivat saada täyden korvauksen kärsimästään vahingosta, sekä poistamaan esteitä ja pienentämään kustannuksia vahingon todistamisessa, samalla harmonisoiden eri jäsenmaissa toimivien yritysten oikeussuojan tasoa. Tarkastelen pro gradu –tutkielmassani kilpailuoikeudellisen vahingonkorvauksen kehitystä sekä uuden EU:n vahingonkorvausdirektiivin vaikutuksia erityisesti vahingonkärsijän näkökulmasta, eli sitä kuinka direktiivi vaikuttaa vahingonkärsijän mahdollisuuteen saada korvausta kärsimästään vahingosta, joka johtuu EU:n kilpailusääntöjen rikkomisesta. Lisäksi tarkastelen lyhyesti direktiivin tuomia muutoksia Suomen lainsäädäntöön. Tutkielmani loppupäätelmä on, että vaikka vahingonkorvausdirektiivi ei täydellisesti paranna vahingonkärsijän asemaa, se selkeyttää monella tavalla kilpailuoikeudellisten vahingonkorvauskanteiden nykyistä tilaa, ja saattaa tietyssä määrin rohkaista vahingonkärsijiä hakemaan korvausta kärsimästään vahingosta.

Logistics Cost Optimization of Road Freight Shipments in a Consumer Goods Company

In the industry of the case company, transportation and warehousing costs account for more than 10% of the total cost which is more than on average. A Finnish company has an understanding that by sending larger shipments in parcels, they could save tens of thousands of euros annually in freight costs in Finland’s domestic shipments. To achieve these savings and optimize total logistics cost, company’s interest is to find out which is the cost efficient way of shipping road shipments of certain volumes; in parcel boxes or on pallets, and what should be the split volume determining the shipment type. Distribution center (DC) costs affect this decision and therefore they need to be also evaluated to determine the total logistics cost savings. Main results were achieved by executing activity-based costing-calculations including DC and road freight costs to determine the ideal split volume with which the total logistics cost is optimal. Calculations were done for Finland’s DC, separately for two main road freight destinations, Finland and Sweden, which cover 50% of road shipment spend. Data for calculations was collected both manually and automatically from various internal and external sources, such as the company ERP system and logistics service providers’ (LSP) reporting. DC processes were studied in practice and compared to model processes. Currently used freight rates were compared to existing pricing models and freight service tendering process was evaluated by participating in the process and comparing it to the models based on literature. The results show that the potential savings are not as significant as the company hoped for, mainly because of packing work increasing DC labor cost. Annual savings by setting ideal split volume per country would account for 0,4 % of the warehousing and transportation costs of shipments in scope of this thesis. Split volume should be set separately for each route, mainly because the pricing model for road freight is different in each country. For some routes bigger parcels should be sent but for some routes pallets should be used more. Next step is to do these calculations for remaining routes to determine total savings potential. Other findings show that the processes in the DC are designed well and the company could achieve savings by executing tenders more efficiently. Company should also pay more attention to parcel pricing and packing the shipments accordingly.

Boulevard to broken dreams, Part 1: the Polonoroeste road project in the Brazilian Amazon, and the World Bank's environmental and indigenous peoples' norms

ABSTRACT Before the mid 1980s the World Bank conceived "nature" as something to be "conquered" and "environment" as a source of resources for "development". By the late 1980s the Bank incorporated norms of environmental sustainability and indigenous peoples' protection into its mandate, and other development-oriented IOs followed. This two-part paper describes how a fight over the Polonoroeste road project in the Brazilian Amazon - inside the Bank, between the Bank and NGOs supported by the US Congress, and between the Bank and the government of Brazil -helped to generate the far-reaching change of policy norms. The first part describes how the project was designed as an innovation in sustainable development in rainforests; and how it provoked a firestorm inside the Bank as it moved towards project approval.

Standardized electrical tests for electrical equipment in road vehicles Case: Visedo Oy PowerMASTER M-frame

Electrical road vehicles were common at the begin of the 20th century but internal combustion engines took a victory from electrical motors in road vehicles. The acknowledgement of the environment, and the price and the availability of the crude oil are reasons for the comeback of the electrical vehicles. Advancement in industrial technology and political atmosphere in EU as the directive 20--20--20, which consists of reducing fossil emission, increasing renewable energy and increasing the energy efficiency, have made the electrification popular again. In this thesis tests based on standard ISO 16750--2 electrical loads for electrical equipment in road vehicles are made for Visedo Oy's PowerMASTER M-frame power electronics device. This device is designed for mainly drive trains in mobile work machines and marine vessels but can be used in other application in its power range which also includes road vehicles. The functionality of the device is tested with preliminary tests which act as a framework for the tests based on standards.
